    I have part of the query working, but we also need to include results that do not have data in that table and column.

    "Be sure to return employees that do not have a manager listed."

    I can return a list of the employees with a manager, but can't get the names to appear of those that do not have a manager.

    Basically, it needs to look like this:

    EmpFirstName EmpLastName Manager
    Test Test Manager1
    Test2 Test2 Manager2
    Test3 Test3 null

    How do I get it to show a null value?

    Hopefully your instructor has covered outer joins.
